Crowdsourcing contests allow firms to seek ideas from external solvers to address their problems. This research examines solvers’ use of developmental feedback from different sources and of different constructiveness when generating ideas in contests. I theorize a source effect in solvers’ feedback use where they use seeker feedback more than peer feedback

[Online Information](https://bm.hkust.edu.hk/bizinsight/tag/online-information)
Among the inputs that executives rely on to run competitive organizations, a particular type resists classification: ideas. Companies need a steady supply of ideas, and they often turn to external venues for help. Say, for instance, a company is developing an advertising campaign that needs art and text to convey a targeted message. If the company lacks the

However, with the increased popularity of crowd-based ideation contests, in which “seekers” engage “solvers” to come up with solutions to creativity and innovation-related problems, this is no longer the case. Various studies show that outside solvers are capable of developing
